Integrity loss via repeated graphics register loads
Published May 15, 2026 · Updated May 15, 2026
A TOCTOU race in the graphics interface of affected AMD processors and GPUs allows local users to cause loss of integrity. Repeated register loads create a timing window between the interface's check and use operations, although AMD has not identified the specific registers or state involved. Exploitation requires a local, highly privileged attacker to win a difficult race; AMD has not disclosed the exact data or graphics state that can be altered.
